Question

A certain television is advertised as a 59-inch TV (the diagonal length). If the width of

the TV is 49 inches, how tall is the TV? Round to the nearest tenth of an inch.

Answer 1

32.9 inches

Explanation:

this can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base = 49

c = hypotenuse = diagonal = 59

l² + 49² = 59²

l² = 59² - 49²

3481 - 2401 = 1080

find the square root

32.9 in
